Thanks,
We should still specify Aligned if the corresponding AVX instruction
requires an aligned operand. ISTR that this is not the case for
MOVNTDQ, so your patch is correct. I'll check the SDM more carefully
next Monday.
The explicitly aligned/unaligned instructions have an A or a U to
indicate this (e.g. MOVDQU = explicitly unaligned, MOVDQA = explicitly
aligned, MOVNTDQ = default).
